Investigators believe 35-year-old Goulet had just shot to SCPD detectives to death at his apartment, grabbed their guns, put on body armor, and stole the detectives' car when police tracked him down here on Doyle Street Tuesday.

Goulet had ditched the car and was fleeing on foot when officers found him just before 4 p.m. When Goulet opened fire, officers unleashed a barrage of bullets and killed him, Sheriff Phil Wowak said.

Goulet's father said his son was a "ticking time bomb" who had contempt for police and swore he would never go back to jail.

At 3:30 p.m. Tuesday, Det. Loran "Butch" Baker and Det. Elizabeth Butler went to Goulet's apartment at 822 Branciforte Dr. to question him about a sexual assault against one of his co-workers. They had no warning that the suspect would swing his apartment door open and open fire.
